The naming rights for the Portland Timbers’ stadium gets the headlines.

But the operating agreement between the Timbers and the stadium’s owner, the city of Portland, allows the Major League Soccer franchise to secure naming rights for all sorts of real estate in the building.

The team can sell naming rights "within the Stadium's perimeter walls,” the operating agreement says. And the Timbers have exercised this provision vigorously.

Terms of those real estate parcel deals in the publicly owned stadium are not known. Similarly, neither the team nor Providence Health & Services will say how much the health organization is paying over the agreement’s 15-year term to call it Providence Park. The two entities held a news conference Monday to announce the new name, replacing Jeld-Wen Field, and to say Jeld-Wen would stay on as a Founding Sponsor of the MLS football club.

Other naming rights opportunities remain in and around the stadium, said Mike Golub, Timbers chief operating officer.

Specifically, the team is looking for a naming rights partner for the plaza at 20th Avenue and Morrison Street. Also, the operating agreement specifically says the team can sell naming rights to the press box.

Before settling on stadium location, choosing patterns and picking out furniture, Golub said the team and the sponsor discuss the sponsor’s objectives.

“That’s a level of strategic understanding,” he said. “We try to put together a sponsorship that helps them meet those objectives.”

The operating agreement also specifically says the team can sell the naming rights for the stadium’s playing field. And though the Timbers’ stadium once was called Jeld-Wen Field, Golub said the field naming rights are not for sale.
